Sustainable Materials for School Uniforms

With the growing awareness of environmental sustainability, schools are increasingly seeking eco-friendly alternatives for their uniforms. Sustainable materials can significantly reduce your school’s carbon footprint while promoting a greener future. In this article, we’ll explore the top sustainable materials for school uniforms and share real-life examples of schools that have successfully made the switch with our help.

Organic Cotton

Organic cotton is a popular choice for sustainable school uniforms due to its eco-friendly production methods. Unlike conventional cotton, organic cotton is grown without harmful pesticides or synthetic fertilisers, reducing its environmental impact. The Arbor School, for example, has incorporated organic cotton into their uniforms, demonstrating their commitment to sustainability and reducing the use of toxic chemicals.


Kapok is a natural and sustainable material, derived from the fluffy fibres cultivated from the fruit grown of the kapok tree. It is lightweight, soft, and hypoallergenic, cotton-like material and is an excellent choice for school uniforms as it uses far less water to grow than organic cotton, and is especially good for students with sensitive skin. As a fast-growing, low-maintenance plant that doesn’t require pesticides or fertilisers, kapok is one of the most environmentally friendly options available.

Recycled Polyester

Recycled polyester is an alternative to virgin polyester. It is typically made from recycled plastic bottles, reducing waste and conserving resources. Fairgreen International School has incorporated recycled polyester into their PE kits, showcasing their dedication to reducing plastic waste. By using recycled polyester, schools can promote a circular economy and reduce the demand for new plastic production. However, it is important to note that once a plastic bottle is turned into a piece of clothing, it is unlikely that it will be recycled again. Recycled polyester also releases microplastics when worn and washed.

Regenerated Nylon

Regenerated nylon, such as ECONYL®, is created by recycling waste materials like fishing nets, fabric scraps, and industrial plastic. By using regenerated nylon in school uniforms, schools can help reduce waste, conserve resources, and lessen the demand for new plastic production. Not only is regenerated nylon an eco-friendly choice, but it’s also durable, lightweight, and comfortable. We typically use this material to make swimwear.

Recycled Materials

By using materials like recycled cotton and recycled wool in your school uniforms, you can conserve resources and reduce waste. Recycled cotton is created by breaking down pre- or post-consumer cotton waste and turning it into new yarn. Similarly, recycled wool is made by collecting and reprocessing wool scraps or old garments.


Lyocell is a sustainable material derived from the wood pulp of a eucalyptus tree. Its closed-loop production process recycles water and solvents, reducing waste and environmental impact. Lyocell is not only eco-friendly but also soft, breathable, and comfortable to wear, making it an ideal choice for school uniforms. It is important to ensure that the lyocell you source is from responsibly managed forests.


Hemp is a highly sustainable material, grows quickly, requires minimal water, and is naturally resistant to pests. The fibres produced from hemp plants are strong, durable, and biodegradable. By incorporating hemp into your school uniforms, you can create long-lasting, eco-friendly garments that reduce our reliance on synthetic materials.
